High-resolution spectroscopy of luminous blue supergiants in Local Group galaxies has become feasible with the new generation of 8–10m class telescopes and dedicated instrumentation (VLT/UVES and Keck/HIRES). We present a (re)analysis of objects in NGC6822 and M 31 by non-LTE/LTE spectrum synthesis. Detailed stellar parameters, chemical abundances, stellar wind properties and reddening values of single stars in different galactic environments are obtained. This work is a case study for analyses of future observations with efficient multi-object facilities like FLAMES on the VLT that will allow an effective use of telescope time.
